February 3, 1918.

next 8 beats, when a fairly uniform shortening occurred. The curve 

 for the standing transition is, in general, not unlike that shown for the 

 majority of the other subjects. The final cycle measured has a dura- 

 tion of 1.19 seconds, which is slightly longer than the standing cycles 

 preliminary to walking. 



In the walking transition curve for Vea (figure 100), the maximum 

 shortening of the pulse cycle appears to have been reached at the 

 eighth beat, with a duration of 1.00 second, which is maintained 

 through the twelfth cycle. At the thirteenth cycle the photographic 

 tracing shows that Vea^s heart skipped a beat and in measuring the 

 duration of the double cycle in which the missing thirteenth beat 

 occurred, the average for two beats has been taken although only one 

 beat (the fourteenth) showed on the record. This pulse cycle is 

 marked by an asterisk (*) in the curve. It is seen that the heart tried 

 to make up for this skip by a quickening of the rate in the succeeding 

 two cycles, the duration showing a change from 1.02 to 0.96 second. 

 This is the only instance of a skipped beat noted in all the records. 

 With this exception, the curve of Vea is not unlike that of the others 

 in this group.
